What is the greatest common factor of 3, 4 and 5?
WebThe greatest common factor (GCF) of a set of integers is defined as the greatest integer that divides each number of that set of integers. The GCF can be obtained as follows: 1. Factor the integers into their prime factors. 2. Write the factors in the exponent form. 3. Take the common bases each to its lowest exponent. WebGCF (3,9) = 3. We will now calculate the prime factors of 3 and 9, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 3 and 9. GCF Calculator. First Number and Second Number. and. WebHere, the greatest common factor is. 7 x 7x Express each term as the product of the GCF and its other factor. 21x + 14x 2 = 7x(3x) + 7x(2) Factor the polynomial. Use the distributive property to factor out the greatest common factor . 7x 7x(3x) + 7x(2) = 7x(3x + 2) Check this factorization by multiplying and , obtaining the original as the answer. can goose be eaten rare
